, 1 This invention relates to newand useful im* provements in attachments for paint brushes and the primary object of the present inventionl is to provide a device that will support the head of a brush raised above the bottom wall of a container and therebyprevent the sediment on the bottom wall of a container froml contacting the v"bristles of a brush.

Another important object of the present invention is to provide a pair of clamping members that are yieldingly held against the head of a brush and which members are perforated to permit turpentine, kerosene or the like tocirculate freely through the members and a brush received by the members.

A further object of the present invention is to provide a device for retaining the head of a 'brush raised above the bottom Wall of a container and which is quickly and readily applied to or removed :from the head of a brush in a convenientmanner.

A still further aim of the present vinvention is to -provide a paint brush attachment that will increase the life of a paint brush and which is simple and practical in construction, strong and reliable in use, neat and attractive in appearance, small and compact in structure, relatively inexpensive to manufacture, and otherwisewell adapted for the purposeslfor which the same is intended. V

Other objects and advantages reside inthe details of construction and operation as more -fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals reiertolike parts throughout, and in whichz" Figure l is a perspective view showing the present invention applied to a. brush;

Figure 2 is a longitudinal vertical sectional view of the present invention and with dotted lines showing theA pressure plate moved away from the base plate;

Figure 3 is a transverse horizontal sectional` view taken substantially on the plane of section line 3-3 of Figure 2; and,

Figure 4 is an enlarged detail sectional view taken substantially on the plane of section line 4-4 of Figure 3.

Referring now to the drawings in detail, where` in for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral I represents the present brush attachment generally, including an elongated substantially rectangular and perforated base plate I2 having spaced parallel side portions or flanges I4. The flanges I4 are provided with outer side edges I6 that slope downwardly toward the lower end portion of the base plate I2.

A pair oi spaced parallel transverse 'slots I8 are provided in the outer edges I6 .of each ofthe side ilanges I4 and the material between these slots IB constitute tongues or arms 20 having depressions 22 for a purpose which will later be more fully described. The tongues 20 are disposed interme# diate the ends of the flanges I4 as shown best in Figures 1 and 2 of the drawings.

Adjacent the upper edges of the side anges I4 there is provided furthery slots or notches 24 and the material Abetween the slots 24 and the upper edges of the side flanges I4 constitute tongues or arms 26 having depressions 28 that will bear against the side edges of a brush head 29.

A transverse stop 39 is provided at the lower end portion of the base plate I2 and the stop r30 is also perforated to permit turpentne, kerosene or the like to circulate therethrough. A bearing extension 32 depends from the stop 30 and will rest against lthel bottom wall iof afcontainer in order Ato retain the base plate I2 and stop 30 raised above the bottom Wall of a container when the instant structure is in use. f

A 'pressure plate 34 is associated'with the base plate I2 and the pressure plate 34 is perforatedto permity turpent-ine, kerosene or'th'e liketo circulate freely through the plates I2 and 34 as well as a brush disposed between the plates I2 and 34. The pressure'plate '34 isprovided at its lowerv end with'a pair of ears 36 having'trunnions or pivots 38 thereon that V'enter apertures 40 provided in the lower ends gf the side'flanges I4, A finger grip 42-is provided-at the upper end ofthe pressureV plate"347and constitutes a'means whereby the pressure plate may be moved away from the base plate I2 for the insertion of the brush 29 between the plates I2 and 34.

In practical use of the present invention, the plate 34 is swung outwardly from the plate I2, to its dotted line position as shown in Figure 2, whereupon the brush 29 is placed against the base plate I2 and between the side ilanges I4. The depressions 28 of the iingers 26 will yieldingly bear against the side edges of the brush head 29 in order to retain the base plate I2 relative to the brush head.

' Next, the pressure plate 34 is moved against the brush head and is held clamped against the brush head by the fingers 20, it being understood that the depressions 22 will bear against the outer face of the plate 34 in order to retain the same urged against the brush head. Next, the instant attachment and brush are inserted into a suitable container having turpentine, kerosene or the like therein and the bearing extension 32 will contact the bottom wall of the container in order to retain the brush head and plates l2 and 34 raised above the bottom wall of the container.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention'as herein described and the scope of the appended claims.
